Microsoft Virtual Server is a virtualization solution that facilitates the creation of virtual machines on the Windows XP and Windows Server 2003 operating systems. Originally developed by Connectix, it was acquired by Microsoft prior to release.

Virtual Machines are created and managed through a web-based interface.

The current version is Microsoft Virtual Server 2005 R2. New features in R2 includes Linux guest operating system support, Virtual Disk Precompactor, SMP support, x64-bit Host OS support (but not Guest OS support), the ability to mount virtual hard drives on the host OS and additional operating systems including Windows Vista.

[edit] Current limitations

The maximum number of supported simultaneous Guest OS's is 64.

Although the software runs in x64 mode on hosts with x64 processors on Virtual Server 2005 R2, it cannot virtualize an x64 processor in a Guest.

It also makes use of SMP, but does not virtualize it.

It does not currently allow guest servers to use more than 1 CPU.

[edit] Version history

On April 3, 2006, Microsoft made Virtual Server Enterprise Edition a free download[1], in order to better compete with the free virtualization offerings from VMware and Xen.

At the moment, Microsoft is working on Service Pack 1 for Microsoft Virtual Server 2005 R2; Beta 2 is currently available for download through Microsoft website [2].

Microsoft Virtual Server R2 SP1 (in beta) will support both Intel VT (IVT) and AMD Virtualization (AMD-V)[3].
